In dimensioned lumber construction, the rim joists are the same depth, thickness and material as the joists themselves; in engineered wood construction, the rim joists may be oriented strand board (OSB), plywood or an engineered wood material varying in thickness from 1 inch (25 mm) to as much as 1 + 3 ⁄ 4 inches (44 mm), though they are ...
Invented in 1969, the I-joist is an engineered wood product that has great strength in relation to its size and weight. The biggest notable difference from dimensional lumber is that the I-joist carries heavy loads with less lumber than a dimensional solid wood joist. [1] As of 2005, approximately 50% of all wood light framed floors used I-joists.
Waffle slabs are preferred for spans greater than 40 feet (12 m), because, for a given mass of concrete, they are much stronger than flat slabs, flat slabs with drop panels, two-way slabs, one-way slabs, and one-way joist slabs. [2] Section of a waffle slab including beam, ribs, and column head
LVL can also be used in combination with gluelam as an outer gluelam tension lam to increase the strength of the gluelam beam. [1] However, due to the fact that the assembly adhesives limit the penetration of chemicals typically used to treat outdoor-rated lumber, LVL may not be suitable for outdoor load-bearing use — rotten LVL joists were ...
A finished tilt-up building. Tilt-up, tilt-slab or tilt-wall is a type of building and a construction technique using concrete.Though it is a cost-effective technique with a shorter completion time, [1] poor performance in earthquakes has mandated significant seismic retrofit requirements in older buildings.
A study led by Mayo Clinic found a “widening gap between lifespan and healthspan" among 183 countries. The lead researcher and another doctor discuss the drivers of poor health late in life.
A plank used in a building as a horizontal supporting member that runs between foundations, walls, or beams to support a ceiling or floor is called a joist. The plank was the basis of maritime transport : wood (except some dense hardwoods ) floats on water , and abundant forests meant wooden logs could be easily obtained and processed, making ...
